The Digital Europe Programme action is still improving the Re3gistry software and has supported the preparation of the study and the implementation of the “Federation of registries”, a missing item in the software market.

The Register Federation Tool is a modular solution designed to support the centralised management of extensions and reference codes. Fully compatible with Re3gistry (v2+), it ensures technological neutrality, promotes interoperability, and enables semantic integration across complex data ecosystems, aligning with European Data Spaces initiatives. Built on the RoR (Register of Registers) specification, it leverages W3C standards such as DCAT and SKOS for structured and interconnected registry management.

Key Features
- Compatibility: Fully compatible with Re3gistry (v2 onwards), offering on-demand RoR descriptor formats.
- Descriptor Files: Allows metadata and data about registries and registers, including their relationships, to be included in RDF/XML documents.
- Search Functionality: Enables searching within different registers and their items.
- Access Options: Provides access to RoR through both graphical user interface and API.
- Interoperability: Facilitates the integration of information from various reference code systems without altering their technical setup, requiring only the exchange of a common descriptor file.
- Benefits: Particularly useful for complex data ecosystems and upcoming European Data Spaces, promoting semantic interoperability across organisations.
RoR descriptor file
RoR stands for Register of Registers.
This specification is based on:
- W3C Data Catalog vocabulary (DCAT) for modeling entity registries (dcat).
- W3C Simple Knowledge Organization System (SKOS) for modeling entity registers (skos) and items (skos).

Download the code
The module is integrated into the Re3gistry source code as a deployable component. Follow these steps to download it:
- Visit the Repository: Go to the Re3gistry GitHub repository.
- Access the Code: Click the Code button on the repository page.
- Choose a Download Method:
- Select Download ZIP to download the entire repository as a ZIP file.
Or, choose Clone to copy the repository to your local system using Git. Use the command:
bash Copy code git clone https://github.com/ec-jrc/re3gistry
- Set Up the Module: Check the repository and module documentation for instructions on installing dependencies and setting up the module.
Background
Initially developed as a testbed to consolidate national extensions of INSPIRE Directive data models, comprising:
- The tool itself
- Best practice documentation
- Conformance classes for RoR Descriptor files.
The tool supports INSPIRE implementations requiring code list extensions and provides an interactive testbed for exploration.
Overall, the Register Federation Tool enhances the capabilities of the Re3gistry parent software, fostering efficient data management and interoperability across diverse datasets and organisations.
